Talladega Nights is fucking terrible. Promised so much (Cohen and Ferrell) and just didn't deliver but for about 4 good moments.
Also another recommendation from me that's not really an Apatow sort of comedy...or even a movie at all, is to just watch "Always Sunny in Philadelphia" if you want stupid comedy. It's like a live action South Park mixed with Seinfeld on crack.
Okay left field, The Room http://www.imdb.com/title/tt0368226/ Pretty much funny because it's so bad. Was actually meant to be a serious film. Hilarious though.
Due Date is worth a watch when nothing else is on. That bloke just plays Alan the whole movie though.
Paul, Year One, Due Date, Dinner for Schmucks, Date Night, The Naked Gun and Superbad (best Judd Appatow film after Pineapple Express.)
